SpeaD 2026
The Complete Loudspeaker Design Platform

Redrock Acoustics has launched a completely revamped version of SpeaD — a comprehensive loudspeaker design platform that consolidates every subsystem of a driver (motor, voice coil, spider, cone assembly, and system response prediction) into a single unified application. Built on .NET 8 with a modern WPF interface, SpeaD is the successor to the legacy SpeaD that has been a tool of choice for professional loudspeaker engineers for decades.
